Abstract
A paver hopper flap suspension system has a number flaps attached to the hopper frame. A cable restraint line is attached to the flaps. A tensioning system is attached to the cable restraint line. The tensioning system allows the flaps to distort as the loading truck body engages the hopper entrance. Once the truck exits the hopper entrance the hopper flap suspension system causes the flaps to spring back to their original shape. The suspension system may include a torsion spring biasing the flaps into a vertical position. The tensioning system may include a tension adjuster. Using this system the flaps are not torn and hold the asphalt in place as the loading trucks dump asphalt into the hopper.
